Northeastern Pennsylvania, where I live, has a reputation for a strong Mafia presence, but very little violence -- at least not locally. The link below represents the first published in-depth account of local organized crime of which I'm aware:

Russell Bufalino (1903-1994) headed what became known as the "Pittston family" (Pittston is a modest-sized, closely-knit, predominately white-ethnic community halfway between Wilkes-Barre and Scranton, with a reputation for modest education and little "social conscience") for many years. Bufalino succeeded Joseph Barbera (remembered as the owner of the hunting lodge near Apalachin, New York,which was the site of the 1957 "gangland convention"); Barbera succeeded Santo Volpe.
The "Pittston family" reportedly had mixed loyalties, operating at various times in partnership with Philadelphia, Buffalo, and the five New York families, and a connection between Bufalino and Philadelphia hired-killer Frank Sheerin is often mentioned when the disappearance of Jimmy Hoffa comes up. Organized crime is also often cited in conjunction with what's left of the anthracite industry.
But in sixty years of living nearby, I can recall only a handful of what appeared to be organized crime-relate incidents of violence, most of them in the Hazleton area about twenty miles to the south.
My home community of Berwick has an Italian-American enclave of about 3 x 8 blocks on the west side of a large foundry complex which dominated local industry for many years. It was common knowledge (so much so that the local newspaper once did a feature on the man) that there was "someone to see" if you were of certain extraction and "needed a favor". But the activity was very low-key; for example, during the mid-1970's,several small businesses in that neighborhood had plastic adapters which, when slipped over a gas-pump nozzle, allowed the cheaper "regular" gasoline to be dispensed into the tanks of newer vehicles requiring unleaded gas.
That was about as "noticeable" as the evidence got.
